Abstract

The oomplexes (C6F5)2HgL (L = 4,4'-dimethyl-2,2'-bipyridyl, 2,2'-biquinolyl, 2,2':6',2"-terpyridyl, 2,4,7,9-tetramethyl-1,lO-phenanthroline, ethylenediamine,
o-phenylenediamine, diphenylamine, pyridine, 4-cyanopyridine, triphenylphosphine,
triphenylphosphine oxide, or 1,2-bisdiphenylarsinoethane), (C6F5)HgL2 (L = di-2-pyridylamine), and [(C6F5)2Hg]L (L = bisdiphenylphosphinomethane or bisdiphenylarsinomethane)
have been prepared, and their constitution, solution stabilities, and structures studied, together with those of the known complexes (C6F5)2HgL (L = 2,2'-
bipyridyl, 1,lO-phenanthroline, or 1,2-bisdiphenylphosphinoethane). Coordination of
triphenylarsine oxide to bispentafluorophenylmercury in solution has also been detected, but the complex could not be isolated.
